The slope of the current line is -2/7. To find the slope of the line perpendicular to it, find the negative reciprocal of the slope. So it would be 7/2. The y intercept or the b would remain the same so the equation would be y=7/2x+8. Hope this helps.

Answer:

The slope of this line would be 7/2

Step-by-step explanation:

In order to find this, you need to know that perpendicular lines have opposite and reciprocal slopes. This means we take the slope of the original line (-2/7) and change the sign to get 2/7. Now we flip the fraction to get 7/2, which would be your new slope.

Omar has 2 3/4 cups of dough to make dumplings. If he use 3/16 cup of dough for each dumpling, how many whole dumplings can Omar
andrey2020 [161]

Answer:

14

Step-by-step explanation:

Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.
